Using label references is preferred when override settings from the
included dtsi.

The pinctrl nodes require some extra opaque arguments for the pull up and drive
strength values.
Introduce a new header file and convert the device trees to replace these
opaque numbers by defines.

Replace the various raw GPIO flags by their definition in the common
dt-bindings header.

On the Hummingbird A31 board, the RTL8211E ethernet phy has its reset
line connect to a gpio pin, instead of floating like on other boards.
Add the stmmac properties for describing the reset gpio.
The reset delays were taken from the RTL8211E datasheet.

The current GPL only licensing on the DTSI makes it very impractical for other
software components licensed under another license.
In order to make it easier for them to reuse our device trees, relicense our
device trees under a GPL/X11 dual-license.

This adds support for the A31 Hummingbird:
http://www.merrii.com/en/pla_d.asp?id=172
The Merrii A31 Hummingbird is a development board based on the
Allwinner A31 SoC with multiple USB ports through a USB hub chip,
a uSD slot, a 10/100/1000M ethernet port, an AP6210 WiFi/BT chip,
TV-in, HDMI, VGA, audio in/out ports, and LCD/CSI headers.

[wens@csie.org: enable usbphy, ehci0, ohci0 for on-board usb hub;
add pcf8563 rtc node; add comments for i2c0 and mmc0 pull-ups;
correct ethernet phy address to 0x01; drop uart2 (BT chip has
no power) and uart3 (no device); use proper commit message]
